The cutter-blade may be selectively received in the rabbet 54, the inner ends of the teeth of the serrations resting on the annular shoulder 55 for centrally locating the'cutterblade on the filler-block with the projections 56 received-in spacesbetween the teeth, for forming driving connection between the filler-block and-the cutter-blade. This is the relation of the parts shown in Fi 15.

The cutter-blade can therefore e secured either to the pulley 45 or the filler-block 46.

(Compare Figs. 12 and 15).

A clamping plate 61 is received about the spindle and is provided with an endwise ex-- tending annular flange 762 received against the inner portion of the cutter-blade, and forming a space 63 between the clamping plate and the part to which the cutter-blade is clamped. v w

A clamping-plate 64 is received'about the other end ofthe'spindle and is provided with an endwise extending annularflange 65. This flange is protectingly received in the rabbet 54 of the filler-block, or in the Nuts 68, 69, are threaded over the threaded ends 70, 71,,ot' the spindle toward each other for clamping the inner raceways 40, the inner spacing collar '41, the end spacing collars 42, the pulley 45, the filler-block 46, the cutter-blade 47, and the clamping plates 61, 64, together on the spindle, for rotating in the balls of the ball-bearings. There is sufficient clearance, as shown by the's aces 72, between the'respective ends of the earing-shell and the pulleyand filler-block, to permit such rotation.

The pulley '45 and the filler-block 46 are arranged to be'interchangeably positioned on the spindle, with the projections 52, 56, respectively thereon extending outwardly.

. The cutter-blade is received about'the projections' on the pulley or on the filler-block to which 'it'is secured, at one end ofthe bearing-shell, the projections on the other of said partsextending endwise outwardly at the other end of the bearing-shell and havthe annularflange 65of the clamping plate 64 received thereover for forming a :smooth outer face for the rotating assembly.

(Figs. 12, '14 and 15)."

- The parts are made interchangeable "for reasons to-be presently described. An arm- 78 extends upwardly'and forwardly from a plate 7 9 fixed to the bearing.-

' piece by screws 80. This arm extends alongside the I cutter-blade.

(See 1 Figs. 4, 5 and A guard 81 is-secured to the arm and is provided with a groove 82 in whichthe outerperiphery of thecutter-blade is received, the' guard having side plates 83, 84, at the respective sides of. the cutter-blade: "(Fig 9). Theplate 84 is extended beyond the through which a clamp-bolt 86 extends into a threaded bearing 87 at the outer end of the arm, a washer 88 being received between the head of the bolt and the plate. (Figs. 4, Sand 10). The slot extends lengthwise 01" the plate, for permitting adjustmentof the guard up and down with relation to the axis of the rotary cutter-blade. The guard is also adjustable in and out toward and from the axis of the rotary cutter-blade, which adjustment is exemplified as a pivotwise adj ustment on the bolt 86.

The adjustment permits the guard to be adjusted toward the axis of the cutter-blade as the cutter-blade is worn or becomes smaller in diameter during use.

The guardis provided with a notch 90 intermediate of its ends. This notch extends inwardly past the outer periphery of the cutter-blade. It is provided with a flaring mouth 91 and the walls 83, 84,at said notch may be tapered, as at 92, for readily directing the parts to be cut into-the notch. The notch extends through both walls of the guard. (Figs. 4 and 9).

A finger 93 is on the base 21 and is provided with a slot 94 into which the rotary cutter-blade extends. The slot 94 is in the same plane with a slot 95 in the base 21, the outer-periphery of the rotary cutterblade rotating in both said slots. (Figs. 4 and 7). The finger is adjustable toward and from the cutter-blade, as by having a clamp-bolt96located in the slot 95 and having threaded connection 97 with the finger for clamping the finger in adjusted positions to the base. The finger may be adjusted in or out toward or from therotary cutterblade for locating the outer end of the slot 94, a desired distance from the outer periphery of the cutter-blade and for accommodating the position of the finger with relation to the diameter of the rotary cutter-blade.

The lower end of the guard is spaced from the finger by a feeding-space 98, (Figs. 4 and 10), and the height of this feedingspace is adjusted by up and down adjustment of the guard 81. I A rearguard 101 is provided for the rotary cutter-blade. It is shown as a plate about the outerperiphery of the cutterblade. It has a flange 103 through which clamp-bolts 104 are received into threaded apertures in the base for clamping the rear guard to the base. (Figs. 6, 10 and 11).

Grinding wheels 108 are mounted on axles 109, journaled in bearings 110, on a yoke 111 of an arm 112, pivoted on a pivot-bolt 113 received through a: flange 114 on said arm and a flange 115 extending upwardly from the plate 79.- (Figs. 4, 6, 10 and 11). A spring 116. is located in a recess 117 between said flanges for normally raising the arm 112 and normally raising the grinding is exemplified as an" electric motor 131 mounted on a support 132 to which the momum wheelsaway from-the cu tter-blade. An adjustable stopscrew 118 is threaded in a lug 119 on 'saidwarin and is arranged to contact a lug 120 on thefiange 115.- The stop-screw is held in adjusted positions by "a spring 121. The arm 112 is providedwith ahandlev 122E01 "depressing saidarrn and moving the winding wheels against the peripheral cuttmgedgeoit the cuttr-ir-blade when it is desiredto' sharpen the latter. The movement of thegrinding wheels toward the cutter-bladeis limited by said stop! f (The grinding wheels are arranged to move in a grinding space 125 between the upper ends *of the guards Bland 101'. Protecting fingers 126 extend from. theyoke $11 at" the respectivesides of the cutterlade.

Our inventionjcontemplates themse o t a plurality of the cutter units on a cutterstand and presenting said cutter units-in opposite directions, so that they may be simultaneously used from opposite sides of the stand. further contemplates the rotation of] the various cut'ter blades from "an intermediate driving agency. (Figs, 1, 2 and The driving agency tor sisadj ustably secured. The rotor of the electric motor is provided withpul leys 133, 134, located side by side. The support is mounted on a =flo'rstand 135 provided at, its upperendwith a seat 136 to which the support is securedby bolts 137.

which is preferablyheavy and of large diameter to rigidly support the parts mounted thereon, It is shown with wide spreadfeet otwhich theremay be for instance four spread equal distances from the Iniddleoi.

The floor-stand is provided with an adjustable post2'141, shownifornied in two sections 142, 143, united by a clamp bearingpiece' 144 having bearings 145, 146, thereinior the respective sections of the post, the sections of the post being clamped in thebearing-piece by set-bolts 147 ,1'48Q The 1 "upper post-section extends downwardly base. i H l The supp orting rodis located in bearings 151in the support -l32, an'd is'fixed insaid bearings by setbolts152.

These cuttenunits havetheirparts interchangeably arranged so that they may be locatedat the ohterbnds of either of the tion, whatwe claim as new secure by Letters Patent, is:=

located in opposite arrangement and its pulley is located at the other end of said bearing shell. This brings the pulleys of the respective cutter units in line with the respective pulleys on the motor shaft, so that therespective belts may bereceived thereover and run true therewith.

The pulleys are shown as grooved pulleys,

the grooves "thereof tapering inwardly, and the belts are preferably rubber belts oftriangular cross-section. Oneof thebelts may have the stretches of its loop crossed so "as to rotate both cutter-blades with the outer portions 'ofjtheir outer peripheries moving downwardly.

In eperation an operator mayv stand at each side otthe stand in front ofthe respec' tive "cutter units. The cloth or ragswhich it is intended to cut into wiping cloths are flied by'the operators upon the fingers 93 through the feeding spaces 98. In case an operator finds any buttons, hooks, buckles or'any other hard articles on the material which he is cutting,- he feeds the connecting portion between such articfes and the :eloth "or rag into the feeding notch 90, the button or other yarticlebeing at one side of the guard 81 andthefbody of the cloth 01" rag "at the other side ofisaid guard, the cloth or rag beingpushed rearwardly so that "the button or Y otherarticle is severed from" the cloth or-raga The. button or other article may be at either side of the guard. 4 3 l -Suitable safety guards, not-showmare provided-forthebeltsand pulleys.
